I just cleaned and reoiled mine, and I have an ever so slight whistle coming from the engine bay consistent with acceleration. Nothing anyone else would notice, but it's driving me crazy. I refitted the filter, but I'm still getting the whistle. I may just buy a new filter.

I don't mean to thread jack - I love this product.
